The Derry brothers and Kimberly Spellman, 32, also of Atlantic City, who was arrested with them, were indicted on five additional charges for possession of illegal drugs and a handgun on the day they were arrested, Feb. 11, 2013: possession of heroin, possession of heroin with the intent to distribute, possession of heroin with the intent to distribute within 1,000 feet of school property, conspiracy to distribute heroin and possession of a weapon while in the course of conspiring to distribute heroin, said authorities.
